PROBLEM TO BE SOLVED: To provide a charger system capable of suppressing consumption of electric power as thermal energy when the electric power from a solar energy generator is charged into a storage battery, and suppressing wasting of electric power generated by the solar energy generator.SOLUTION: A charger system 1 includes a solar energy generator 10, a DC/AC converter 60 which converts the electric power from the solar energy generator 10 into an AC power, batteries 20, 30 for accumulating electric power from the solar energy generator 10, and a DC/DC converter 80 for converting a voltage of the electric power from the batteries 20, 30. The battery includes a main battery 20 and a sub battery 30 whose internal resistance is higher than the main battery 20.SELECTED DRAWING: Figure 1 【課題】太陽光発電機からの電力を蓄電池へ充電する際に、電力が熱エネルギーとして消費されることを抑え、且つ、太陽光発電機により発電された電力の無駄を抑えることができる充電システムを提供すること。【解決手段】太陽光発電機１０と、太陽光発電機１０からの電力を交流の電力に変換するＤＣ／ＡＣ変換器６０と、太陽光発電機１０からの電力を蓄電するバッテリ２０、３０と、バッテリ２０、３０からの電力の電圧を変換するＤＣ／ＤＣ変換器８０と、を備え、バッテリは、メインバッテリ２０と、メインバッテリ２０よりも内部抵抗が高いサブバッテリ３０と、を有する充電システム１である。【選択図】図１
